Narrative:

RNAV arrival. At skebr intersection on the skebr arrival to las, the autoplt turned the aircraft slightly right, attempting to proceed direct shand 10 DME fix on final for runway 25L. LNAV was deselected and aircraft was manually turned for kepec. I asked the first officer to install kepec as the next waypoint when ATC called. The time to react and make the manual correction at skebr was approximately 10 seconds. At ATC's request, the approach was completed via radar vectors. A subsequent phone call to las approach resulted in a cordial exchange of information. I was informed that skebr and tragr intxns are both 'problems' for 'only company aircraft.' further, the crew that took the aircraft at the end of the day allowed they had the exact same thing happen, at the exact same spot on their current trip. Las approach indicated there were 'no issues' resulting from this event, but asked that the information be passed on to company. Notes: the route was checked after being installed at the gate in ont. It appears that all the arrival legs after skebr were deleted when the arrival runway (runway 25L) was selected. I should have caught this sooner. Do we need a software fix? Upon review, it seems when the route is selected, the skebr arrival being activated does not include the runway 25L waypoints even after runway 25L has been selected and activated. The skebr arrival must be selected again and activated before the runway 25L waypoints appear. Supplemental information from acn 572344: I did load the route (ONTLAS01), then selected the ILS runway 25L approach to las. I do not recall if the entire approach was in the FMC at that time. Due to the short flight (we began descent at the top of climb) and high workload (ATIS, in-range call, opc computation, etc) I did not verify the points on the arrival and back up the captain flying.

Title: A TRACK DEV IS CAUGHT EARLY BY THE CREW AND IS VERY FAMILIAR TO ATC ON THE SKEBR RNAV 2 ARR TO LAS, NV.

Narrative: RNAV ARR. AT SKEBR INTXN ON THE SKEBR ARR TO LAS, THE AUTOPLT TURNED THE ACFT SLIGHTLY R, ATTEMPTING TO PROCEED DIRECT SHAND 10 DME FIX ON FINAL FOR RWY 25L. LNAV WAS DESELECTED AND ACFT WAS MANUALLY TURNED FOR KEPEC. I ASKED THE FO TO INSTALL KEPEC AS THE NEXT WAYPOINT WHEN ATC CALLED. THE TIME TO REACT AND MAKE THE MANUAL CORRECTION AT SKEBR WAS APPROX 10 SECONDS. AT ATC'S REQUEST, THE APCH WAS COMPLETED VIA RADAR VECTORS. A SUBSEQUENT PHONE CALL TO LAS APCH RESULTED IN A CORDIAL EXCHANGE OF INFO. I WAS INFORMED THAT SKEBR AND TRAGR INTXNS ARE BOTH 'PROBS' FOR 'ONLY COMPANY ACFT.' FURTHER, THE CREW THAT TOOK THE ACFT AT THE END OF THE DAY ALLOWED THEY HAD THE EXACT SAME THING HAPPEN, AT THE EXACT SAME SPOT ON THEIR CURRENT TRIP. LAS APCH INDICATED THERE WERE 'NO ISSUES' RESULTING FROM THIS EVENT, BUT ASKED THAT THE INFO BE PASSED ON TO COMPANY. NOTES: THE RTE WAS CHKED AFTER BEING INSTALLED AT THE GATE IN ONT. IT APPEARS THAT ALL THE ARR LEGS AFTER SKEBR WERE DELETED WHEN THE ARR RWY (RWY 25L) WAS SELECTED. I SHOULD HAVE CAUGHT THIS SOONER. DO WE NEED A SOFTWARE FIX? UPON REVIEW, IT SEEMS WHEN THE RTE IS SELECTED, THE SKEBR ARR BEING ACTIVATED DOES NOT INCLUDE THE RWY 25L WAYPOINTS EVEN AFTER RWY 25L HAS BEEN SELECTED AND ACTIVATED. THE SKEBR ARR MUST BE SELECTED AGAIN AND ACTIVATED BEFORE THE RWY 25L WAYPOINTS APPEAR. SUPPLEMENTAL INFO FROM ACN 572344: I DID LOAD THE RTE (ONTLAS01), THEN SELECTED THE ILS RWY 25L APCH TO LAS. I DO NOT RECALL IF THE ENTIRE APCH WAS IN THE FMC AT THAT TIME. DUE TO THE SHORT FLT (WE BEGAN DSCNT AT THE TOP OF CLB) AND HIGH WORKLOAD (ATIS, IN-RANGE CALL, OPC COMPUTATION, ETC) I DID NOT VERIFY THE POINTS ON THE ARR AND BACK UP THE CAPT FLYING.
